Been struggling with this issue on and off for a year or two. A couple of high order ascii characters keep inserting themselves onto the screen, at the cursor position usually but not necessarily. It is random, sometimes not for a whole session, sometimes every few minutes. Takes the form of one of these two characters -- --- ���or ééé --- Will pop into being without a finger on the keyboard. I've just been cursing and deleting them, but it has happened when I am editing .int and .kbd files, and if I missed it I could have a real problem debugging if something screws up. Running the latest version of VDOS-Xy on Win11 13th gen chip Have tried a few things --- massaging config.txt, changing code pages (thanks Carl), even swapping keyboards -- but the problem persists. So, is this a known problem? Have I missed some simple fix? Any ideas for a workaround? Thanks, Harry Favor
